Mirror a striped lv

[Vorb]

I have a logical volume in a volum group, which consists of 2 striped PVs. I need to migrate these PVs to another array. How can i do it online? Is it possible to mirror a striped LV on HP-UX 11.31?

Hi:

Yes, in 11.31 striped and mirrored logical volumes are supported.  See the manpages for 'lvcreate(1M)' and 'lvextend(1M)' for more information.

Regards!

And is it possible to disable stripe and to migrate data to one big PV?

No, you cannot disable striping. 

Once traditional striping has been enabled (via lvcreate with the '-i' and '-I' options) on an LV then only way to remove it, that I am aware of, is to back up the data, recreate the LV, then restore the data.

The exception is if you used distributed stripes (lvcreate -D y).  These can be disabled via 'lvchange -D n' on the logical volume.
